Advantages
of Laser printer
The most important factor in favor of laser printers is probably the
speed. These printers are and remain faster than inkjet printers. Companies
with many print jobs will unquestionably opt for a laser printer. A further
advantage is that replacing the toner in this printer is normally cheaper than
replacing cartridges for inkjet printers. The laser technology also ensures
that the printed material is less likely to run than when printed on an inkjet
printer.
Disadvantage of laser printer
However, there are also disadvantages to laser printers. The price is a
fair bit higher, especially when it comes to color printers. Moreover, an
inkjet printer in some cases offers more possibilities than a laser printer.
The conclusion is that it is always important to weigh up the advantages and
disadvantages of both printer systems. A company will often go for a mixed
solution: a few laser printers and also a few inkjet printers. That way
everyone is happy.
Advantage of thermal printers:
o No issues with ribbons wrinkling when printing
o Less physical inventory to store
o Eliminates issue of ordering/using wrong label
and ribbon sizes
o Direct Thermal Printers don’t need capacity for
ribbons so they are more compact
Disadvantage
of thermal printers:
o Labels cannot withstand long exposure to
sunlight or extreme heat. Leave a gas station receipt on your dashboard and you
will see it fade from the exposure. These receipts use similar direct thermal
technology.
o Even without sun exposure, the labels will fade
over long periods of time. For labeling boxes kept in inventory for years,
direct thermal is not the best choice.
o Print speeds tend be slower.
o Depending on the market environment, direct
thermal labels can cost a little more than thermal transfer labels with
ribbons.
o Putting acrylic adhesive tape over a direct
thermal label will cause the label to fade.
